DRAG.

SPECIFICATION forming part of Letters Patent No. 653,658, dated July 17,1900. Application filed March 1'7, 1900. Serial No. 9 ,096. (No model.)

known as drags, which are used for transporting heavy objects withoutthe trouble of suspending them from wheeled trucks; and it has for itsobject to produce a device of this kind which will be of great strengthand which may be renewed or repaired with but trivial expense; and itconsists in the improved construction and novel arrangement of parts ofa drag, as will be hereinafter more fully set forth.

In the accompanying drawings, in which the same reference-numeralsindicate corresponding parts in each of the views in which they occur,Figure 1 is a top plan view of a drag embodying my invention. Fig. 2 isa longitudinal sectional View of the same. Fig; 3 is a perspectivedetail view of the front portion of the drag.

Referring more particularly to the draw ings, 1 indicates the head orfront portion of myimproved drag, which is preferably made of steel oriron, the front portion of which is contracted toward a point and curvedor bent upward in the form of a sled-runner, and the rear portion isflat and perforated, as at 2. The lower surface of the head, exceptingwhere it is perforated, is perfectly flat and curved, so as to ridefreely over the ground and to pass over any obstructions which it mightmeet in its forward movement. The upper surface of the head is providedwith Vertical flanges 3 and 4, one of which, 3, extends entirely aroundthe edge, except at the rear, and the other ones, 4, intersect eachother at the center of the head, one of them extending longitudinally ofthe head at the center and the other one extending transversely acrossthe head. The flange at the forward end is of greater thickness or areain cross-section than the other flanges, and the front of the head isprovided with a ring 5 or other means of attaching the draftingmechanism thereto.

Fitting between the flanges at the rear of the head is the forward endof the bottom 6, which is preferably formed from two wooden planks, therear ends of which are secured together by means of a cross-piece 7; Thecenter rib or flange of the head is so narrow that when it is fittedbetween the two planks the space between the planks is so small'as tomake the drag substantially solid throughout, and, if desired, theadjacent edges of the planks may be slightly out out for the receptionof the flange, so as to permit the remaining portion of the edges toabut against each other. The perforations through the head arepreferably made angular and flaring toward the under surface, so thatthe bolt-heads by means of which the planks are secured to the head canbe made angular and slightly tapered, so as to fit in said perforationswithout requiring them to project below the surface, the thickness ofthe head being suflicient to give the bolts a good strong support orhearing. When constructed in this manner, it will be seen that myimproved drag can be cheaply constructed and that it will possess verygreat strength and that it may be renewed or repaired very easily. Asthe rear portion of the drag is preferably made from wood to better holdthe stones or other substances which may be loaded upon it, the facilitywith which this portion of the drag may be renewed is of considerableimportance. The formation of the rear portion of the head for thereception of the forward ends of the planks adds greatly to the strengthand rigidity of the parts, and especially in turning or pulling the draglaterally, when the flanges of the head will engage with the ends of theplanks and assist the bolts in holding the planks in position. Theflanges will also add to the strength of the head itself, and thuspermit of the head being made of less thickness than would be requiredwithout the flanges. By making the heads of the bolts angular they willbe prevented from turning when it is desired to replank the head if thebolts should have become rusted or battered and are diflicult to remove.

Although Ihave shown what I consider to be the most desirable form forconstructing my drag, yet I reserve to myself the right to make suchchanges and alterations therein as will come within the scope of myinvention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

In a drag, the combination, with an upwardly-curved head, the rearportion of which is provided with countersunk angular perforations andthe upper surface of the head is provided with a flange extending aroundthe edges except at the rear, and the central portion is provided withtwo intersecting flanges one of which extends longitudinally of the
